We print the possible flags for set_mempolicy() which is pretty simple 
since there's only one possible flag at any given time, but we don't print 
any possible flags for mbind().  If we are to start printing lazy 
migrate-on-fault then we should probably print the other flags as well, I 
just don't know how long we want lines in numa_maps to be.
